+Freescale i.MX6 DW MIPI DSI Host Controller
+===========================================
+
+The DSI host controller is a Synopsys DesignWare MIPI DSI v1.01 IP
+with a companion PHY IP.
+
+These DT bindings follow the Synopsys DW MIPI DSI bindings defined in
+Documentation/devicetree/bindings/display/bridge/dw_mipi_dsi.txt with
+the following device-specific properties.
+
+Required properties:
+
+- #address-cells: Should be <1>.
+- #size-cells: Should be <0>.
+- compatible: "fsl,imx6q-mipi-dsi", "snps,dw-mipi-dsi".
+- reg: See dw_mipi_dsi.txt.
+- interrupts: The controller's CPU interrupt.
+- clocks, clock-names: Phandles to the controller's pll reference
+ clock(ref) and APB clock(pclk), as described in [1].
+- ports: a port node with endpoint definitions as defined in [2].
+- gpr: Should be <&gpr>.
+ Phandle to the iomuxc-gpr region containing the multiplexer
+ control register.
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+[2] Documentation/devicetree/bindings/media/video-interfaces.txt
+
+Example:
+
+ mipi_dsi: mipi@21e0000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "fsl,imx6q-mipi-dsi", "snps,dw-mipi-dsi";
+ reg = <0x021e0000 0x4000>;
+ interrupts = <0 102 IRQ_TYPE_LEVEL_HIGH>;
+ gpr = <&gpr>;
+ clocks = <&clks IMX6QDL_CLK_MIPI_CORE_CFG>,
+ <&clks IMX6QDL_CLK_MIPI_IPG>;
+ clock-names = "ref", "pclk";
+ status = "okay";
+
+ ports {
+ port@0 {
+ reg = <0>;
+ mipi_mux_0: endpoint {
+ remote-endpoint = <&ipu1_di0_mipi>;
+ };
+ };
+ port@1 {
+ reg = <1>;
+ mipi_mux_1: endpoint {
+ remote-endpoint = <&ipu1_di1_mipi>;
+ };
+ };
+ };
+ };
